Ahh, I’m just sitting hear drinking a cold home brew. Thinking to my self that Lager is brewed at the same temp as any other beer, rolling boil. But it is fermented at cooler temperatures over a longer period of time. Yest definitely influences the flavor of beer. But no more then grains, process or hops. I would say the largest influence on flavor is cleanliness. JMHO
Having won 12 ribbons at the WA State Fair, I can tell you that's not necessarily true.
Cleanliness is paramount in all fermentation...but temperature is critical when it comes to any beer. It's important to ferment at the lowest temp the yeast will tolerate and still be active enough to crowd out nefarious bacteria and "other" yeasts. When fermented too warm you end up with those crappy Belgian Ales:)
Garbage, each and every one lol
Seriously, Cleanliness and Temperature are key.
